Torsion classes in the cohomology of KHT Shimura varieties
Pascal Boyer
A particular case of Bergeron-Venkatesh's conjecture predicts that torsion classes in the cohomology of Shimura varieties are rather rare. According to this and for Kottwitz-Harris…
Two-sided infinite-bin models and analyticity for Barak-Erdős graphs
Bastien Mallein, Sanjay Ramassamy
In this article, we prove that for any probability distribution on one can construct a two-sided stationary version of the infinite-bin model (an interacting parti…
Witt and Cohomological Invariants of Witt Classes
Nicolas Garrel
We classify all invariants of the functor (powers of the fundamental ideal of the Witt ring) with values in , that it to say functions compatible…
Scalar curvature via local extent
Giona Veronelli
We give a metric characterization of the scalar curvature of a smooth Riemannian manifold, analyzing the maximal distance between points in infinitesimally small neighborho…
Lifting Theorems and Smooth Profinite Groups
C. De Clercq, M. Florence
This work is motivated by the search for an "explicit" proof of the Bloch-Kato conjecture in Galois cohomology, proved by Voevodsky. Our concern here is to lay the foundation for a…
Kinetic entropy for the layer-averaged hydrostatic Navier-Stokes equations
Emmanuel Audusse, Marie-Odile Bristeau, Jacques Sainte-Marie +1
We are interested in the numerical approximation of the hydrostatic free surface incompressible Navier-Stokes equations. By using a layer-averaged version of the equations, we are…
